Peeps typically make their appearance in the springtime, with numbers peaking in April. Despite their ubiquitous distribution and social nature, their migratory paths, wintering, and breeding areas are little known.

During their breeding season, Peeps can easily be found in suburban backyard habitats, where they lay clutches of colorful eggs in nests of brightly-colored plastic grasses. Adult and immature peeps can be quickly located by their sweet calls and neon plumage.

Scientists recognize only the familiar “yellow” form of peep; but there is currently support in the ornithological community for granting separate species status to the blue, teal, pink, and purple forms of Peep, currently considered color morphs.
Although Peeps are heavily consumed, their populations appear to quickly rebound in subsequent years and therefore they are not a species of conservation concern.
